The Shopard joint, also known as the transverse tarsal joint, is a joint in the foot that connects the tarsus to the metatarsals. It is a complex joint consisting of two separate joints.
The medial joint is located between the first cuneiform bone and the first metatarsal bone. The lateral articulation is located between the third cuneiform bone and the third metatarsal bone. These two joints work together to provide mobility and stability to the midfoot.
The Chopart joint plays an important role in the biomechanics of the foot during walking and running. It allows the foot to adapt to uneven surfaces and absorb shock upon contact with the ground. Damage to this joint can lead to pain, instability, and impaired foot function.
